1. Search in Rotated Sorted Array Suppose an array sorted in ascending order is rotated(轮流,循环) at some pivot(枢轴; 中心点) unknown to you beforehand(提前; 事先). (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). You are given a target value to search. If found in th...

leetCode 33. Search in Rotated Sorted Array(c语言版本) bingo酱 I am a fighter 来自专栏 · leetcode每日斩 题目大意: 给定一个旋转升序的数组,所谓旋转就是假设把头和尾连接起来,然后找到最小那个数开始,往后开始就是升序的,直到再回到最小那个数为止。这样看起来就像一个环一样。 然后,现在给定一个数,...
LeetCode 33 Search in Rotated Sorted Array 题意 思路 代码 总结 题意 给出一个数组,该数组是由一个升序排列的数组以某个轴旋转后得到的。例如4 5 6 7 0 1 2是由0 1 2 4 5 6 7旋转(我认为是交换)后得到的。给你一个目标值target,要求判断数组中是否存在这个值,存在的话给出它的位置,否则返回-...
You may assume no duplicate exists in the array. 原问题链接:https://leetcode.com/problems/search-in-rotated-sorted-array/ 问题分析 这个问题在之前的文章里有讨论过。总的来说是基于这么一个思路。当我们将一个排序后的数组循环移位之后,其实它就构成了两个递增的段。我们用二分查找法去查找元素的时候...
